To all whom it may concern:

Be it known that I, DANIEL J. HARDING, a citizen of .the United States,residing at Louisville, in the county of Jefferson and State ofKentucky, have invented certain new and useful ImprovementsinStamp-Cancelers; and I do declare the following to be a full, clear,andexact description of the invention, such as willenable others skilledin the art to which [o it appertains to make and use the same, referencebeing had to the accompanying drawings, and to letters or figures ofreference marked thcreon,whi'ch.form a part ofthis specication.

: Figure 1 of the drawings is a representation of this invention, and isa side view. Fig. 2 is a bottom view. through the' stamp-cancelen 6 aredetails.

This invention relates to vinstruments for canceling stamps, checks,Src.; and it consists in the construction and novel arrangement ofparts, as described, and pointed out in the claims.

In the accompanying' drawings, the letter A designates the metallic bodyofthe instrument, which may be provided with a metallic or woodenhandle, B, which is usually attached to said body by means of itsthreaded eX- tremity C, the latter engaging the threaded bearing D inthe body yof the instrument. Usually I provide on one side of the bodyan4 or. ydinary datingstamp, E, which is set upon a spring or springsand works upon a guide or guides.

As usually constructed, the body A consists of a cap-plate, G, and theboXingcF and II, respectively, for the dating-stamp and for thecanceler; or the body may be single, being pro- Figs. fi, 5, and

4o vided only with the boxing H for the cancelen The boxing H ispreferably cylindrical, and is formed with a central bore, I, inopposite sides of which are formed the oblique camgrooves a a, whichhave an angular deviation from the axial plane of about fifteen ortwenty degrees, the object being to give a positive and quick action tothe cutter K, whose stem P is provided with the studs c c on oppositesides, engaging said cam-grooves. Above the 5o central bore, I, in theboxing is the interspace i, which gives play to the cutter-stem and Fig.3 is a vertical section guide'rods when the impact is made. Said boxingHis also formed with guide-apertures d d, parallel with the central boreand adapted to receive the guide-rods L of the bearinghead N. Theseguide-apertures are enlarged in their lower portions to receive thesprings e, which engage the bearing-head and serve to lbear it outwardwhen not pressed down upon the stamp or paper. In the lower face of the6o bearing-head 'is usually formed an annular groove or seat,f, for theannular pad g, of cork or other proper material. The bearing-head is, asshown, usually made of considerably greater `diameter than the cutter,which works in the central portion thereof,iin order to assist insecuring`the true action of the latter, and to provide a guard toprevent the cutter from being forced too 'deeply into the envelope orother paper upon which the instrument is act- 7o ing. To insure greatersecurity in this particular the head N is provided with an outercircular guard, h, which is 'formed with oblique lslots 71, throughwhich are passed the screws k,

which engage threaded perforations of the head. When these screws areloosened, the annular` guard can be turned to adjust its heightsrelative to that of 'the cutter, so that the latter can be given just asmuch action as may be required. In" this manner the head 8o may beadjusted to permit the cutter to act on the stamp of an envelope withoutcutting the material of said envelope under the stamp.

The central bearing, l, ofthe head N is usually' cup -shaped or formedwith a conical 8: bottom shoulder to provide a seat for the underportion of the cutter-headm, whichis also usually conical in form,theobject being to provide a bearing against which the cuttencan easily andreadily revolvewhen the impact is 9o made. As usually constructed, thisbearing Z is made in the form of a bushing let'into the central openingof the head N.

The cut-ter K consists of the stem portion P and the head m. rlhe stemportion is provided with the studs or projections c c on opposite sides,to engage the cam-grooves of the boxing H. v It is also formed Withastop, o, at

its inner end, to engage the inner end of the central bearing of theboxing, to prevent the 10o cutter from moving outward beyond a certainpoint. Usually this stop is made in the form of a largeheaded screw,which is secured in a central threaded perforation of the stem, asshown. The stem is also provided with trans verse pin or stop s, whichserves a similar purpose with reference to the bearing-head N,preventing the cutter from projecting beyond the face of the latterbeyond a certain point, It will be observed that in this constructionthe instrument .is adapted to be readily and easily taken to pieces forrepair or other purpose.

The head of the cutter is usually somewhat larger in diameter than thestein, as hereinbcfore indicated. Its face, which is set a littleoutward or above the face of the head N, is formed with radial cuttingedges, indicated at v '0, made by removing V-shaped portions of the faceof the cutter, as shown. The cutting edges are usually in the sameplane, and are rectilinear or so related to each other that their actionwill be uniform, the cuts made by them being of the same depththroughout.

The action of the cutter is rotary. In the normal position thebearing-head N is held outward or away from the boxing by the springaction. W'hen, however, the impact is made by a quick smart blow, theinstrument being struck downward upon the stamped envelope-or othermatter, the boxing is forced v downward toward the bearinghead, and,moving along the stern of the cutter, acts upon the latter by theengagement of its cam-grooves to forcibly rotate the cutter when inintimate or forcible contact with the stamp, cutting the vlatter to suchdepths as may be permitted by Y the stops,respectively,for thebox-bearing and the head-bearing, substantially as specified.

2. In a stamp-cancelen the combination, with the bearing-head carrying arotary cutter centrally located, of the adjustable annular guard havingoblique slots and the screws whereby said annular guard. is secured tothe bearing-head, substantially as specified.

In testimony whereof I aflix my signature in presence of two witnesses.
